Description

Technical Field

[0001] The present invention belongs to the technical field of container space expansion, and specifically relates to a container space expansion method and system with track-type side panel linkage control. Background Art

[0002] With the rapid development of the logistics and transportation industry and the continuous expansion of multi-functional container application scenarios, how to improve the functionality and utilization efficiency of containers through space expansion technology has become a research hotspot. Existing container space expansion technologies still have certain shortcomings in terms of implementation methods, ease of operation, and structural stability. Especially in scenarios that require frequent unfolding and folding, traditional manual or simple mechanical expansion methods are difficult to meet the needs of efficient and precise space control. For example, the "Expandable Vehicle-mounted Mobile 4D Cinema System" with publication number CN105442875B proposes a container expansion solution based on a flap structure. By flipping down the flap and connecting it to the bottom of the container, a space for placing expansion boxes is formed. However, the expansion method in this technical solution relies on the physical support of the flap, and its expansion space is limited and the operation is relatively cumbersome, lacking the ability of automatic linkage control; at the same time, the flap, as the main load-bearing structure, may have problems with insufficient load-bearing capacity and stability during long-term use, affecting the reliability and safety of the system. In addition, the "Agriculture and Photovoltaic Integration System of Movable Distributed Containers" with publication number CN112119905B achieves vertical expansion of the interior space of the container through a built-in lifting mechanism, which can provide multi-layer planting areas to maximize the use of space. However, this technical solution mainly focuses on the layered utilization of the internal space and does not involve the space expansion function of the side panel linkage control; its expansion method relies on a complex telescopic frame and metal grid floor structure, which increases the overall weight and puts higher requirements on transportation and installation; at the same time, the operation process of this solution is relatively complicated and lacks an intelligent linkage mechanism, making it difficult to adapt to the needs of rapid deployment and flexible adjustment. The above problems show that the existing container space expansion technology still has shortcomings in terms of automation level, structural flexibility, operational convenience, and adaptability to application scenarios. Therefore, there is an urgent need to develop a new space expansion method and system to solve the problems existing in the existing technology and meet the needs of modern logistics and transportation and multi-functional container application scenarios for efficient and intelligent space expansion technology.

DETAILED DESCRIPTION

[0014] The present invention provides a container space expansion method and system with track-type side panel linkage control. The core of the system is to realize the linkage expansion or retraction operation of the container side panels through the track sliding mechanism, and to combine the locking mechanism and hydraulic support device to ensure the stability and load-bearing capacity of the expanded space. Figure 1 To the attached Figure 3 Specific embodiments of the present invention are described in detail.

[0015] First, according to Figure 1 As shown in the flow chart, the specific implementation process of the present invention starts with the operation of the track sliding mechanism. The track sliding mechanism is one of the core components of the entire system, which is mainly composed of a hydraulic cylinder transmission assembly, which is used to drive the container side panels to move along a predetermined track. In actual applications, the operation of the track sliding mechanism can be started by issuing a command from the central processing unit, and the hydraulic cylinder transmission assembly pushes the side panels along the track to unfold or fold after receiving the power. The limit sensor is installed at a key position on the track to detect the moving position of the side panel in real time. When the side panel moves to the preset position, the limit sensor will send a signal to the central processing unit to ensure the accuracy of the unfolding or folding operation. In addition, the user can also adjust the unfolding angle of the side panel according to actual needs, such as unfolding the side panel to 45 degrees, 90 degrees or other specific angles, so as to form an adaptive target space form.

[0016] After the side panel deployment operation is completed, the system enters the structural fixing stage. Figure 1 As shown in the figure, the structural fixing module is responsible for performing this task. When the side panels are deployed into position, the electric locking device automatically receives the locking signal and activates operation. The electric locking device mainly consists of a motor drive unit and mechanical connectors. The mechanical connectors securely connect the side panels to the container body via bolts or other fasteners. To further ensure the stability of the structure, a pressure sensor is integrated into the locking device to monitor the tightening degree of the locking device in real time. If the pressure sensor detects that the locking device has not reached the preset tightening force value, the system automatically adjusts the output power of the motor drive unit until it meets the requirement. In this way, safety hazards caused by loose locking can be effectively avoided.

[0017] Next, the system enters the load-bearing reinforcement stage. The load-bearing reinforcement module uses a built-in hydraulic support device to perform load-bearing reinforcement on the target space form. The hydraulic support device is usually installed at the four corners of the bottom of the container, and each support device is equipped with an independent pressure feedback module. In actual operation, the hydraulic support device is first started and extended downward until it contacts the ground and applies a preset pressure value. The pressure feedback module monitors the working status of the hydraulic support device in real time. If it detects that the support pressure has not reached the preset value, the system will automatically adjust the extension and retraction amount of the hydraulic support device and re-execute the above steps. Once the support pressure reaches the preset value, the system confirms that the load-bearing reinforcement process is complete. This design can not only significantly improve the carrying capacity of the expanded space, but also effectively meet the use needs under complex terrain conditions.

[0018] At the same time, the data acquisition module is responsible for obtaining the operating status data of the track sliding mechanism during the unfolding or folding process. Figure 2 As shown, multi-sensor acquisition modules are distributed across key locations of the track sliding mechanism, including speed sensors, displacement sensors, and vibration sensors. These sensors monitor the operating status of the track sliding mechanism in real time and upload the collected data to the central processing unit via the data transmission module. The central processing unit organizes the received data according to time series and generates an operating status record. The operating status record contains operating parameters of the track sliding mechanism over different time periods, such as sliding speed, displacement, and vibration frequency. This data provides an important basis for subsequent feature extraction and consistency verification.

[0019] The feature extraction module segments the operating status records to produce segmented data. Specifically, the purpose of segmentation is to divide the continuous operating status records into several time segments, each of which corresponds to an operating cycle of the track sliding mechanism. An operating status feature library is then constructed based on the segmented data. The operating status feature library stores multiple key feature points, such as maximum sliding velocity, minimum displacement deviation, and average vibration amplitude. A feature matching algorithm is used to extract key feature points from the operating status feature library, ultimately yielding the operating status features. These feature points can comprehensively reflect the operating status of the track sliding mechanism, providing a basis for subsequent consistency verification.

[0020] The data processing module classifies and labels the operating status features to obtain labeled operating features. The classification and labeling process is completed based on the machine learning model. Figure 2As shown, during the model training phase, the system needs to collect a large amount of track slip data with operating status annotations and perform feature extraction on it to obtain the annotated operating features. The annotated operating features are then divided into training data and validation data. The training data is used to train the machine learning model, while the validation data is used to evaluate the model's performance. During the training process, the machine learning model analyzes the input training data and outputs preliminary analysis results. The system calculates the deviation between the preliminary analysis results and the standard operating status preset in the training data. If the deviation value is greater than or equal to the preset deviation threshold, the parameters of the machine learning model are optimized and the training steps are re-executed. Conversely, if the deviation value is less than the preset deviation threshold, the model performance is evaluated using the validation data. If the model fails the performance evaluation, the amount of training data is increased and feature extraction is performed again; if the model passes the performance evaluation, the model training is confirmed to be complete, and the intelligent control model is obtained.

[0021] The intelligent control module uses a pre-designed intelligent control model to optimize and adjust the track sliding mechanism. Specifically, the intelligent control model first locates abnormalities in the verification results and determines the track sliding mechanism components that need to be adjusted. For example, if the sliding speed of a side panel is significantly lower than that of other side panels, the intelligent control model will determine that the hydraulic cylinder transmission assembly corresponding to the side panel may have a fault. Subsequently, the system sends adjustment instructions to the track sliding mechanism through the control module to dynamically correct the specific faulty components. Adjustment instructions may include measures such as increasing the motor speed, replacing worn parts, or recalibrating sensors. In this way, the system can significantly improve the operating efficiency and reliability of the track sliding mechanism.

[0022] at last, Figure 3 The functional module diagram of the container space expansion system with rail-type side panel linkage control provided by the present invention is shown. The system consists of a space expansion module, a structural fixing module, a load-bearing reinforcement module, a data acquisition module, a feature extraction module, a data processing module and an intelligent control module. The various modules work together to achieve efficient expansion and precise control of the container space. For example, in a certain actual application scenario, the user needs to expand the space of a standard 20-foot container to 30 feet. At this time, the space expansion module activates the rail sliding mechanism and expands the two side panels to 90 degrees respectively to form a new target space form. Then, the structural fixing module firmly connects the side panels to the container body through an electric locking device. The load-bearing reinforcement module activates the hydraulic support device to perform load-bearing reinforcement processing on the expanded space. At the same time, the data acquisition module obtains the operating status data of the rail sliding mechanism and generates labeled operating features through the feature extraction and data processing modules. The intelligent control module optimizes and adjusts the rail sliding mechanism based on the verification results to ensure the stability and reliability of the system.

[0023] In summary, the present invention utilizes a track-based sliding mechanism to achieve the coordinated deployment and retraction of container side panels, incorporating a locking mechanism and hydraulic support device to ensure the stability and load-bearing capacity of the expanded space. Multi-sensor fusion technology is used to acquire operational status data for the track-based sliding mechanism, and an intelligent control model is employed to optimize and adjust the track-based sliding mechanism, further enhancing the system's operational efficiency and intelligence. Therefore, the container space expansion method and system with track-based side panel linkage control proposed in the present invention can achieve efficient expansion and precise control of container space in practical applications.
